Abstract:

It is an important and significant task to improve the efficiency of urban land use for the development of new-type urbanization. This study takes the precise recognition of the influencing mechanism of new-type urbanization in intensive urban land use as a basis, and employs the dynamic principal components analysis to discuss the spatial-temporal evolution of new-type urbanization and intensive urban land use during the period from 2006 to 2011 with the aid of SPSS 19.0 software. Moreover, spatial panel econometrics model is used to reveal the relationship between these two variables on new-type urbanization and intensive urban land use by employing the panel data on 29 provinces of China during the period 2006-2011. Major conclusions can be drawn as follows: (1) In general, both the comprehensive level of new-type urbanization and intensive urban land use show stable upward trends and tend to be convergent; (2) The performances of relationship between new-type urbanization and intensive urban land use are various in eastern, central, western China, and among the three regions. Both the interprovincial gap between the eastern and western regions, and the intra-gap among the three regions are main causes for the overall gap. The spatial-temporal evolution trend reveals that these two variables show a significant geographical agglomeration and incremental clustering characteristic. What's more, the spatial pattern presents a more apparent similarity and synchronization of cluster evolution trend. Besides, the spatial pattern of new-type urbanization has "geographical features of three vertical and two horizontal lines", while spatial distribution of the intensive urban land use shows a gradient in agglomeration from the east to the inland areas; (3) The intensive urban land use has a more significant positive spatial correlation, which shows an upward trend. This implies that new-type urbanization plays a significant role in improving intensive land use both in the whole country and in the regions.
